LUBRICATING DEVICE FOR AI-ILE-BEARII\TGS.

Application filed November 28, 1913.

To (ZZZ whom it may concern:

Be it known that I, Hni'ivnici-i Ponrrnn, a subject of the King of Prussia, residing at 126 Graienberger Allee, Dusseldorf, in the German lilmpire, have invented certain new and useful Improvements in Lubricating Devices for Axle-Bearin 's of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to a lubricating de vice for axle-bearins s, especially those of railway :arriages, of the type wherein grease is supplied to the axle-journal under spring pressure from a receptacle on the axle-box.

The essential feature of the invention consists in the fact that the receptacle containing the grease or like lubricating medium consists of a collapsible tube that is subjected to lateral pressure at its upper and lower ends; this pressure preferably being exerted at its upper end by means 0]": two laterally arranged screws, and at its lower end by rollers subject to the action of weights or springs.

The accompanying drawings illustrate by way of example one constructional form of lubricating device in accordance with this invention, Figure 1 being a longitudinal section, and Fig. 2 a transverse section thereof.

The lubricating grease is contained in a tube a provided with an upward extension 6 wherein there is formed an outlet slot 2' running lengthwise of the axle Z. The upper portion 7) of this extension which bears against the axle Z preferably consists of leather, while in its main portion I) there are provided a pair of recesses or notches b 6,, into which there engage the upper ends of two screws 0 and 0 by means of which the extension 6 is held in position and is at the same time pressed with a suitable degree of force against the axle Z. These screws are preferably provided as shown, with nuts 0,, 0,, that bear against the axle box and by the rotation of which the screws can be moved upward. The tube a, which is guided in a wooden casing 7c is provided at its lower end with a narrowed portion a against which there bears a pair of rollers (Z and d that are carried by sheet metal supports 0 and c and are gradually moved upward as the lubricating substance is consumed. Upward pressure may be exerted on the supports 0 and e and the rollers (Z and (Z' by any suitable loading means, such, for in- Specification of Letters Patent.

stance, as weights or springs. In the example illustrated in the drawings, this pressure is produced by means of two weighted lever arms f and f connected at f2, f2 With another pair of arms h and h respectively passing through apertures 71 h, in the axle box at and hearing at their upper ends 72,, 71,-, against the wooden casing 7? containing the receptacle a. The arms f and 7 pass beneath a rod 9 connecting the two sheet metal supports 0 and e. The casing 70, containing the tube a, is pushed into the axlebox on beneath the axle Z, and the extension 6 with its leather pad 7) placed in position, whereupon pressure is applied to it by means of the screws 0 and 0' forcing it against the axle. The supports 6 and a carrying the rollers (Z and (Z are then placed in position from beneath and the lower arms and f" are placed in engagement with the rod the lever arms f and f, rod 9 and rollers (Z, (Z assume the positions shown in dotted lines in Fig. 2, and thus indicate that the empty tube should be replaced by a full one.

ll hat I claim is 1. In a lubricating device for axle bearings, a collapsible receptacle adapted to con tain lubricant, furnished with an outlet orifine "tor said lubricant and adapted to be inserted in an axle box, screw devices mounted in said axle box, adapted to maintain said lubricant outlet orifice in contact with an axle journaled in said axle box, and to exert pressure on the upper portion of said collapsible receptacle, rollers mounted in upwardly movable supports and adapted to bear against the lower portion of said collapsible receptacle, and means for applying iupwardly directed pressure to said up wardly movable supports and thereby actuating said rollers therein mounted to exert upwardly directed pressure on the lower portion of said collapsible receptacle.

2. In a lubricating device for axle bearings, a collapsible receptacle adapted to contain lubricant, said receptacle being provided with an upward extension having a lubricant delivery orifice formed therein, the upper portion of said extension being composed of leather and adapted to bear against the axle journalcd in said axle box; the lower portion of said extension being provided with. recesses or notches, screw devices adjustably mounted in said axle box and having their upper ends in engagement As the tube is gradually emptied l. l (l with said recesses or notches, a casing inclos ng said collapsible receptacle, and adapted to be lnserted together therewith into said axle box; vertically movable supports, rollers carried thereon and adapted to bear against the lower portion of said rcceptacle, loaded lever devices adapted to exert upward pressure upon said vertically tain lubricant, said receptacle being provided with an upward extension having a lubricant delivery orifice formed therein, the

upper portion of said extension being com- I: posed of leather and adapted to bear against the axle journaled in said axle box, the lower portion of said extension being provided with recesses or notches, screw de vices adjustably mounted in said axle box and having their upper ends in engagement with said recesses or notches, a casing inclosing said collapsible receptacle and adapted to be inserted together therewith into said loaded lever devices adapted to exert upward pressure upon said vertically movable supports and said rollers carried thereon and weights carried by said lever devices for loading the same. i

In testimony whereof I ailix my signature in the presence of two witnesses.
